 ???Another thing I don't quit understand is if difficult can fluctuate why N can not fluctuate, but only keep grow? Is it had to build a model to test it?

Interesting, I don't know the details of the algorithm. But we can modify the codes to test if the
list at http://explorer.yacointalk.com/graphs.htm#tech make sense of Vertcoin.

One poor thing is the memory of Video cards can not grow for this coin, the size of the memory of video cards always determined by the requirement of games.  But the memory of asic can adapt to this coin. But it's the future situation we don't know.


as the other user pointed out, we will simply reduce the number of threads on GPU to accomodate for the new N-factor
for ASICs i'm sure it's a big problem, memory actually takes the biggest number of transistors in the die of those scrypt chips, and that's the reason why they are so cheap and efficent apart from the specific optimization. they work in-cache and are specifically designed.


But why N=8192 for yacoin, the hashrate of 6990 is 0kh/s? Because the hashing algorithm is Scrypt (SHA-3/Keccak512 hash function + ChaCha20/8 mix function)? Thank you.

lol, that coined up.. that really is a thing Cheesy
I bought some VTC so I was trying to withdraw it..
it took me like 15 minutes and I had to put put numerous of orders for withdraw to get it out Cheesy

Just wondering why the memory increase is based on a schedule rather than an adjustment just like the difficulty is for any other coin. What if the near future suddenly provides us ASICs with lots of memory? I must admit I prefer more complex algos (or combinations of algos) that force the usage of GPU/CPU because an ASIC for them would actually be a CPU...
Sorry if this question has been already answered in the previous pages, didn't read them all...

its not about lots of memory in ASICs, but about n factor changing and you can build efficiently ASIC only with predefined N factor.. once it changes, it is useless..
dev is talking about it in article..

We have to hold this coin. It´s innovative so It become the new Litecoin in the future. I am mining and holding.

Thats right.. this coin is just perfect.. no premine, no instamine, no scrypt clone... bright future Smiley)


do you guys see chart on coined up updated?
I still see same pattern as during lunch time.. orders being paired but not displayed on chart.. I dont see any spikes over 0.0005 price etc. although there were trades for even more..

My charts are also stuck. i'm using ff, didn't try anything else.

Its the coin of the future! Most of the other Alternate cryptocurrencies will be long forgotten in a few years but vertcoin will be still kicking!

i'd like to address a possible issue.

looking from this table (results for hd6690 on yacoin)
http://explorer.yacointalk.com/graphs.htm#tech

in november 2015 when vertcoin switches to N=8192 there will be a *huge* drop in hash rate. cpus will continue to mine, while gpu will be useless suddenly.
that will cause confirmation times go to the moon, because hashrate will drop thousands of times suddenly.

ok maybe the new cards like r9 290 will be able to mine until N=16384, but this will only postpone the problem.

start thinking about the kimoto gravity well, it will be necessary even without multipools jumping in....

I think N should be also related to or proportional to the difficulty or something else, but do not adjust it artificially such as by hands or according to the timestamps. Too large N kills every hardware.

6990 and r9 290 have the same size of memory, they will be killed at the same large N=8192.


Well, no the 6990 is 2x2Gb cards in one.r9 290 has double memory per gpu chip.
Vertcoin, sure they increase a bit the memory but not exponentially. And we want everybody to mine, not just those who can afford the new high-end cards, otherwise it's useless, and its the same as having asics...
Maybe a silly question, but when VTC hits N-Factor 8192, why is that a problem for GPUs? The chart indicates a memory requirement of 1MB, compared to 512KB at N=4096. If that's per hashing thread, then at N=4096 a card with 3GB (7950, 7970, etc.) could still run TC=6144 while at N=8192 you would have to drop to TC=3072. You certainly won't get the same performance at lower TC values, but tweaking will almost certainly mean it's not going to be half as fast. Newer versions of cgminer and such will likely also play a role. In other words, there's no magical N-Factor at which GPUs are suddenly unable to perform the hashing calculations. In ten years when we're at N=131072 and using 16MB, a 3GB GPU could still run with TC=192. Then again, ten years ago we were looking at GPUs with a whopping maximum 256MB VRAM, so in ten more years we might be running GPUs with 144GB RAM. :-D

you are right.. nice one

I really hope people with high hashrate willing to drop their hashrate till the diff adjusted .... so it won't go too high for small miners like me Tongue

I don't have a massive hashrate, but unless the price jumps from where it's at now, i would probably stop mining for a while... it won't be as profitable as other coins for me if the diff ends up at 10-12 and the price stays where it is now on CoinedUP. But i would jump back in at a diff lowering or price jump to make it at least comparable to other coins.



I made same mistake when diff jumped from 2 to 5 Cheesy
now I regret it.. I would have had more coins minted on diff 5..

In case people who are new to VTC missed it originally, we have an interview with the dev we posted last week.

http://www.followthecoin.com/interview-creator-vertcoin/





Ou yeah, its must read Smiley
And here are some highlights:

Q:
Unlike almost every other coin launch in recent months, Vertcoin was launched without a pre-mine. A lot of developers use a pre-mine to help cover promotional costs of the coin, as well as further development funding down the road. What was your reason for not doing a premine? And will this impact future development, as there’s no bank of coins saved to provide funding?

devs A:
In my opinion, a pre-mine is not acceptable. I think we need to separate between funding costs and pre-mines. Some people who are creating a coin say they do pre-mines to cover funding. I believe you should get your funding from venture, or the coin community. Let me give an example.

When I launched this coin, I didn’t know how to do marketing. People in the coin community helped me to promote this coin. I am also not a good designer for logo and website, but people are willing to help me create a beautiful logo and website, because they believe in the coin, not because I need to promise them a reward to do so.

Moreover, if the coin’s creator wants to develop a new feature in the future, and cannot find funding from their coin’s community, he or she can seek funding from others willing to put their money into your project if it is a good enough coin or idea.

It would really be a win win for them, they could go snag up some other coins and as soon as the next diff adjust hits they come back and keep pulling in a lot of coins rather than raising it and pulling in less coins.

Before that happens I need to figure out why my CPU is accepting shares but they don't show up in the pool.



actually, seems that they are really doing it.. but probably more accurate would be to tell "he" Cheesy
but yes.. with this quite long diff reterget its good strategy for all of us.. such a small cheat Cheesy
